Step 1: Reagents: Steam (H₂O(g)) Conditions: High temperature (e.g., 300 °C), high pressure (e.g., 60-70 atm), concentrated phosphoric(V) acid (H₃PO₄) catalyst. Step 2: Reagents: Acidified potassium dichromate(VI) (K₂Cr₂O₇/H₂SO₄) or acidified potassium manganate(VII) (KMnO₄/H₂SO₄). Conditions: Heat under reflux. Step 3: Reagents: Concentrated sulfuric acid (H₂SO₄) Conditions: Heat. Step 4: Reagents: Concentrated sulfuric acid (H₂SO₄) Conditions: Heat (e.g., 170 °C). Step 5: Reagents: Hydrogen bromide (HBr) Conditions: Room temperature. Step 6: Reagents: Potassium cyanide (KCN) or Sodium cyanide (NaCN) Conditions: Ethanol (solvent), heat under reflux. Step 7: Reagents: Dilute hydrochloric acid (HCl) or dilute sulfuric acid (H₂SO₄) Conditions: Heat under reflux. 3. Write a balanced chemical equation for the reaction in step 1. CH₂=CH₂(g) + H₂O(g) ⇌ CH₃CH₂OH(g) 4. Write a balanced chemical equation for the reaction in step 2. 3CH₃CH₂OH(l) + 2Cr₂O₇²⁻(aq) + 16H⁺(aq) → 3CH₃COOH(l) + 4Cr³⁺(aq) + 11H₂O(l) (Using acidified potassium dichromate(VI) as the oxidizing agent) 5. Write a balanced chemical equation for the reaction in step 3. CH₃COOH(l) + CH₃CH₂OH(l) ⇌ CH₃COOCH₂CH₃(l) + H₂O(l) 6. Write a balanced chemical equation for the reaction in step 4. CH₃CH₂OH(l) → CH₂=CH₂(g) + H₂O(l) 7. Write a balanced chemical equation for the reaction in step 5. CH₂=CH₂(g) + HBr(g) → CH₃CH₂Br(l) 8. Write a balanced chemical equation for the reaction in step 6. CH₃CH₂Br(l) + KCN(alc) → CH₃CH₂CN(l) + KBr(aq) 9. Write a balanced chemical equation for the reaction in step 7. CH₃CH₂CN(l) + 2H₂O(l) + H⁺(aq) → CH₃CH₂COOH(l) + NH₄⁺(aq) (This is for acidic hydrolysis) What's next?
